Abstract:Aspidistra arnautovii H.J.Tilich var.angustifoliaL.Wu &Y.F.Huang is described and ilustrated as a
new variety of Aspidistrafrom Guangxi,China.The new variety is similar to A.arnautovii H.J.Tilich var.arnau-
tovii,but differs in its blade narrow lanceolate to nearly linear,1.2-2.0cm wide,with ca.9fine secondary veins at
each side,stigma with ca.24smal marginal incisions,upper surface convex.

  With in-depth field expedition,the number of
known species from the genus Aspidistra Ker-
Gawler increases remarkably during the past three
decades.According to our recent knowledge,the
genus Aspidistra encompasses over 100species
with distribution from southern Japan to Peninsu-
lar Malaysia,and the center of diversity in Guan-
gxi,China and adjacent northern Vietnam(Lang et
al.,1999;Li,2004;Tilich,2005,2006,2008;Hou
et al.,2009;Lin et al.,2009,2010;Xu et al.,2010;
Gao &Liu,2011).Plants of Aspidistra are char-
acterized by aperennial habit,conspicuous rhizo-
mes,a variety of fruits and a highly diversified
flower structure(Lin et al.,2010).
Two years ago,the authors came across a pe-
culiar Aspidistra plant without flowers from Shi-
wandashan National Nature Reserve in Guangxi,
and luckily colected its flowering plants in the re-
cent field expedition.Consultation of herbarium
material and relevant literature reveals that its
flower differs from al the known species of Aspi-
distraexcept A.arnautovii,but compared with A.
arnautovii,it also differs in its blade narrowly lan-
ceolate to nearly linear,1.2-2.0cm wide,with ca.

So we confirmed it is a new variety and described
as below.

  Aspidistra arnautovi H.J.Tilich var.angusti-
folia L.Wu &Y.F.Huang is similar to A.arnautovi
H.J.Tilich var.arnautovi mainly by sharing creeping
rhizome,widely campanulate perianth,obconical pistil
and inconspicuous ovary.However,the former can be
easily distinguished from the latter by its much narro-
wer leaf blade.A comparison of the salient characters
of A.arnautovi var.angustifolia and A.arnautovi
var.arnautovi is shown in Table 1.The new variety is
widely distributed on the slopes under dense forest,and
adapted to subtropical monsoon climate.Furthermore,
it is distributed mainly in Shiwandashan Natural Re-
serve,Guangxi,growing wel in this area,and does not
need any additionaly special protections.
